Paediatric voice disorder: who to refer and how to assess? A summary of recent literature.

PURPOSE OF REVIEW: The purpose of this review is to update the reader with recent advances and current opinion on the assessment and management of paediatric voice disorders. RECENT FINDINGS: Access to advanced multidisciplinary paediatric voice clinics has increased over the last decade. Often the assessment is combined between speech therapy/pathology and ENT surgery. Vocal fold nodules remain the most prevalent diagnosis at a paediatric voice clinic, but significant diseases will also present, for example laryngeal papilloma. Recently, more consideration of the psychosocial aspect of voice disorders and evaluation of auditory processing disorders have shown how these can have a negative impact. There also appears to be a lack of parental and teacher awareness of paediatric voice disorders and their significance. SUMMARY: We would recommend multiparametric assessment and analysis of all children with a voice disorder. Most paediatric voice conditions will respond to skilled voice therapy. However, the exact techniques and dosage requires further evaluation and research. Paediatric voice conditions are common and should not be dismissed, as they may represent significant disease, for example papilloma, vagal palsy or have a significant psychosocial impact on the child.

Sintomas vocais, ansiedade e depressão pré e pós-tireoidectomia / Vocal symptoms, anxiety and depression pre and post thyroidectomy / Síntomas vocales, ansiedad y depresión pre y post tiroidectomía

Introdução: Alterações na tireoide e a tireoidectomia podem levar à sintomatologia vocal e emocional.Objetivo: Correlacionar sintomas vocais e traços de ansiedade e depressão pré e pós-tireoidectomia. Métodos: Estudo observacional, longitudinal. Participaram 20 pacientes submetidos à tireoidectomia, ao exame visual laríngeo e à Escala de Sintomas Vocais (ESV) e Escala Hospitalar de Ansiedade e Depressão (HADS) no pré-operatório, pós 1 semana e pós 3 meses, com média de idade de 54,5 anos, maior prevalência do sexo feminino (85%) e tireoidectomia parcial (70%). Resultados: Os pacientes autorreferiram sintomas vocais em todos os momentos, com maior frequência após uma semana e diferença significativa entre o domínio físico pré e pós 1 semana. Na HADS, observou-se maior escore total no pré-operatório e diferença significante nos três momentos, em todos os domínios, com maior diferença entre pré e pós 1 semana. Houve correlação positiva fraca entre os domínios limitação, emocional e escore total da ESV com a subescala de ansiedade pós 1 semana, entre o escore total da ESV e o escore total da HADS e correlação positiva moderada entre os domínios limitação e emocional da ESV com o escore total da HADS após uma semana. Conclusão: Pacientes submetidos à tireoidectomia autopercebem sintomas vocais e traços de grau leve de ansiedade tanto no pré quanto pós 1 semana e após 3 meses de cirurgia com pior autorreferência após uma semana. Quanto maior a autorreferência de sintomas vocais, mais traços de ansiedade o paciente pode apresentar. (AU)

Introduction: Thyroid alterations and thyroidectomy can lead to vocal and emotional symptoms.Purpose: To correlate vocal symptoms and anxiety and depression traits pre and post-thyroidectomy. Methods: Observational, longitudinal study. Participants were 20 patients who underwent thyroidectomy, laryngeal visual examination and the Voice Symptom Scale (VoiSS) and Hospital Anxiety and Depression Scale (HADS) preoperatively, 1 week and 3 months after, with a mean age of 54.5 years, higher prevalence of female gender (85%) and partial thyroidectomy (70%). Results: The patients self-reported vocal symptoms at all times, more frequently after one week and a significant difference between the physical domain pre and post 1 week. In HADS, there was a higher total score in the preoperative period and a significant difference in the three moments, in all domains, with a greater difference between pre and post 1 week. There was a weak positive correlation between the limitation, emotional and total score of the ESV domains with the anxiety subscale after 1 week, between the total score of the ESV and the total score of the HADS, and a moderate positive correlation between the limitation and emotional domains of the ESV with the HADS total score after one week. Conclusion: Patients undergoing thyroidectomy self-perceived vocal symptoms and mild anxiety traits both before and after 1 week and after 3 months of surgery with worse self-report after one week. The greater the self-report of vocal symptoms, the more traces of anxiety the patient may present. (AU)

Introducción: Cambios en la tiroides y tiroidectomía pueden provocar síntomas vocales y emocionales. Objetivo: Correlacionar síntomas vocales y rasgos de ansiedad y depresión antes y después de tiroidectomía. Metodos: Estudio observacional/longitudinal. Participaron 20 pacientes que se les realizó tiroidectomía, examen visual laríngeo, Escala de Síntomas Vocales (ESV) y Escala Hospitalaria de Ansiedad y Depresión (HADS) en preoperatorio, 1 semana y 3 meses después, con edad media de 54,5 años, prevalencia del género femenino (85%) y tiroidectomía parcial (70%). Resultados: Los pacientes informaron síntomas vocales en todo momento, con mayor frecuencia después de una semana y una diferencia significativa entre el dominio físico antes y después de 1 semana. En HADS, hubo mayor puntaje total en el preoperatorio y diferencia significativa en los tres momentos, con mayor diferencia entre pre y post 1 semana. Hubo una correlación positiva débil entre limitación, emocional y total de los dominios de la ESV con la subescala de ansiedad después de 1 semana, entre el total de la ESV y e total de la HADS, y una correlación positiva moderada entre la puntuación de limitación y dominios emocionales de la ESV con la puntuación total de HADS después de una semana. Conclusión: Los pacientes sometidos a tiroidectomía autopercibieron síntomas vocales y rasgos de ansiedad leve tanto antes como después de 1 semana y después de 3 meses de la cirugía con peor autoinforme después de una semana. Cuanto mayor es el autoinforme de síntomas vocales, más rastros de ansiedad puede presentar el paciente. (AU)

Tracking Occupational Voice State with a Visual Analog Scale: Voice Quality, Vocal Fatigue, and Effort.

BACKGROUND: Due to elevated vocal health risk in industries such as call centers, there is a need to have accessible and quick self-report tools for voice symptoms. This study aimed to determine if the concurrent and construct validity of three visual analog scales (VASs) of voice quality and symptoms could be used as a screening tool in call center agents. METHODS: A cross-sectional study was carried out in three call center companies. The Voice Handicap Index-10 (VHI-10) and a vocal hygiene and symptoms survey were administered to 66 call center workers. Further, acoustic parameters including harmonics-to-noise ratio (HNR), smoothed cepstral peak prominence (CPPs), L1-L0 slope, and Alpha ratio were collected. Finally, workers completed three VASs capturing self-perception of vocal effort (VAS-1), voice quality (VAS-2), and vocal fatigue (VAS-3). Linear regression models with bootstrapping evaluated the possible relationship between the three VASs measurements, self-perceived vocal symptoms, and acoustic parameters. RESULTS: VAS-1 scores were associated with HNR and voice breaks, VAS-2 with voice breaks, and VAS-3 with Alpha ratio. Using the area under a receiver operating characteristic curve (AUC), the highest AUC for detecting an altered VHI-10 questionnaire score was observed for the three VASs. Also, the highest AUC for detecting altered CPPs was reached for the VAS-1. CONCLUSIONS: VAS as a self-report instrument of vocal symptoms is related to psychosocial voice impairment and alterations of acoustic voice parameters in call center workers. Such instruments could be easily implemented to identify voice complaints in these populations. LEVEL OF EVIDENCE: 2 (Diagnosis research question) Laryngoscope, 133:1676-1682, 2023.

Measuring Communicative Congruence and Communicative Dysphoria in a Sample of Individuals Without Voice Disorders.

PURPOSE: This study examines communicative congruence and communicative dysphoria in adults who deny having a voice disorder. Communicative congruence is the degree to which a person's communication is consistent with their sense of self/identity. Communicative dysphoria is the psychological entropy resulting from communicative incongruence. We propose that these experiences may influence patients' psychosocial well-being and are thus relevant to the field of speech-language pathology. We hypothesized that both constructs would be normally distributed with an inverse relationship. We also hypothesized that communicative congruence would predict scores on the Center for Epidemiological Studies-Depression (CES-D) scale, subscales of the Big Five Aspect Scales (BFAS; a personality measure), and achieve convergent validity with the Vocal Congruence Scale (VCS). METHOD: Participants (adults 18-70 years) completed the BFAS, CES-D, VCS, and the Voice Handicap Index-10 (VHI-10) before recording a series of speech tasks. Participants' recordings were played back while they responded to questions probing their communicative congruence and communicative dysphoria. RESULTS: The 196 participants were predominantly female (67.3%) and cisgender (96.4%). Communicative congruence was negatively skewed, and communicative dysphoria was normally distributed. Both variables significantly related to each other: More incongruence was associated with more dysphoria. Communicative congruence was inversely related to CES-D scores. The personality metatrait Plasticity related to communicative congruence, as did the domain of Extraversion and the aspects Withdrawal, Enthusiasm, and Assertiveness. Communicative congruence achieved high convergent validity with the VCS. CONCLUSIONS: Counter to our hypothesis, participants reported more congruence than incongruence, but all other hypotheses were supported. Participants who reported incongruence were more likely to report symptoms of depression. These findings suggest that even in a predominantly cisgender cohort, some individuals' mental well-being might relate to how well their communication aligns with their identity. This work may inform future investigations into these constructs and their effects on voice therapy outcomes. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.20739967.

Reflux Symptom Index (RSI) and Singing Voice Handicap Index (SVHI) in Singing Students: A Pilot Study.

OBJECTIVE: To correlate, RSI with SVHI, in a group of singing students, by means of a specific anamnestic questionnaire which analyzes the physical, social, emotional, and economic impacts of voice problems on their lives. This study is a cross-sectional single-center observational study. METHODS: Forty-two modern singing students (26F/16M; average age: 24.9 ± 5.7; range: 16-46 years old) were recruited. A self-assessment of the singing-voice (SVHI) and of reflux symptom (RSI) was performed. RESULTS: Using the validated RSI threshold, 31% of participants were classified as RSI greater than 13 as an indication of suspected LPR. Classifying the SVHI score as proposed in the recent literature (cutoff of 20.35) our sample was a voice disorders prevalence of 71.4%. There was no significant positive or negative relationship between RSI and SVHI total score (rho = 0.238, P = 0.13). Instead, by considering the relationship between the individual items of the two questionnaires, it is highlighted that the item 1 of SVHI was significantly correlated with most of the RSI items (P = 0.0001-0.006). In the same vein, the item 5 of SVHI was correlated to hoarseness and coughing (P = 0.005-0.006). The item 20 of SVHI was significantly correlated with hoarseness, excess mucus in the throat or postnasal drip and with the pharyngeal Globus sensation (P = 0.001-0.005). By aggregating the SVHI item response as a positive response (2-4) versus a negative response (0 or 1) between "RSI pathology classification," a significant association was observed for SVHI item 1 (P < 0.021), item 5 (P < 0.006), item 20 (P < 0.042), item 24 (P < 0.044) item 25 (P < 0.047). These associations were confirmed by univariate binary logistic. Multivariate binary logistic regression confirms that SVHI Item 1, Item 5 were more associated with RSI positive. Based on results, we propose a questionnaire that combines the most relevant SVHI items correlated to LPRD (SVHI-10-LPRD questionnaire). Cronbach's alpha coefficient for the 10 items selected was 0.87; item-total correlation coefficients for each item were in the range of 0.461 to 0.670. CONCLUSIONS: This pilot study shows that, in case of significant RSI for LPR, it is possible to observe a significant association with some symptoms described in SVHI. These results underline that the association of the RSI and SVHI questionnaires administered to singers and singing students, can represent a simple screening to reveal possible alterations of the singing voice correlate to LPR. Moreover, we propose a Singing Voice Handicap Index correlated to LPR (SVHI-10-LPRD). It will be necessary to increase the sample of subjects in the study to confirm these preliminary data.

Development, Validation, and Reliability of the Teacher-Reported Pediatric Voice Handicap Index.

PURPOSE: The purpose of this study was to develop a novel teacher-reported pediatric voice outcome measure and to investigate its psychometric properties. METHOD: In the first stage, a new instrument, the Teacher-Reported Pediatric Voice Handicap Index (TRPVHI), was developed. After item generation, a panel of experts evaluated the items to assess the content validity. Subsequently, the final version of the preliminary instrument was applied to teachers of 306 children (57 dysphonic and 249 vocally healthy) between the ages of 4 and 11 years. Eventually, the construct validity, criterion-related validity, test-retest reliability, and internal consistency of the developed instrument were examined. RESULTS: The items with a content validity ratio less than .8 were modified or removed, and accordingly, the preliminary version of the index was finalized. After the application of the preliminary version, item reduction was made based on the factor analysis. The index is composed of 27 questions and three subscales: Functional, Physical, and Emotional. A significant difference was observed between the dysphonic and vocally healthy children for the TRPVHI scores (p < .001). A positive moderate correlation was determined between the Pediatric Voice Handicap Index and TRPVHI scores. Correlation coefficients between the test and retest scores of the TRPVHI were in the range of .92-.98. Cronbach's alpha values computed to assess the internal consistency were in the range of .94-.98. CONCLUSIONS: The TRPVHI is the only valid and reliable teacher-reported outcome measure of the effects of voice disorders on children. It is anticipated that the deployment of the TRPVHI in conjunction with other subjective tools, both in the initial evaluation and the follow-up of the treatment results, will allow a better understanding of the physical, functional, and emotional effects of voice disorders on children. Furthermore, it can potentially lead further research to enable the use of the TRPVHI for screening purposes.

Voice-Related Quality of Life Is Associated with Postoperative Change in Subglottic Stenosis.

OBJECTIVES: To characterize the impact of subglottic stenosis (SGS) on voice-related quality of life (V-RQOL) and quantify the effect of treatment on voice outcomes. STUDY DESIGN: Case series. METHODS: Retrospective review of SGS patients treated from 1996 to 2018 at a single institution to assess for 1) V-RQOL association with individual patient cumulative treatment number and 2) V-RQOL correlation with treatment type, time between treatments, and degree of stenosis. Analysis included both parametric and nonparametric statistical comparison across treatment types and multivariable and univariate linear regression. RESULTS: Sixty-one patients, predominantly white (93%) and female (93%), were included. Etiology of SGS included idiopathic (61%), iatrogenic (16%), granulomatosis with polyangiitis (16%), and other (7%). The plurality of patients had four or more treatments (44%), with the remainder having one (28%), two (13%), or three treatments (15%). Analysis of change between pre- and postoperative V-RQOL scores was completed for 130 treatments. These included dilation with laser incision (52%), in-office injection (34%), dilation without division (8%), cricotracheal resection (1%), and all other treatment (8%). For every 10% improvement in airway caliber postoperatively, there was a 1.3-point improvement in calculated V-RQOL (r = 0.27, P = .02). After adjustment for treatment type, age, sex, and SGS etiology, this association held (beta = 1.5, P = .02). Change in V-RQOL was not associated with treatment type, treatment number, or time between treatments. CONCLUSION: Patients with subglottic stenosis who have greater degree of change in airway caliber experience greater improvement in V-RQOL scores following treatment. V-RQOL scores are not associated with treatment type or time between individual treatments. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:360-365, 2021.

Voice Quality, Function, and Quality of Life for Laryngeal Cancer: A Prospective Longitudinal Study Up to 24 Months Following Radiotherapy.

OBJECTIVE: To study the potential changes of health-related quality of life (HRQL), voice quality, and communicative function up to 24 months following radiotherapy for patients with laryngeal cancer. METHODS: A total of 28 patients with laryngeal cancer, treated by curatively intended radiotherapy were included in this prospective longitudinal descriptive study. Patients were followed pre-radiotherapy, 12 months, and 24 months post-radiotherapy. At each time point, voice recordings and patient-reported outcome instruments (European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core30, Head and Neck35, Swedish Self-Evaluation of Communication Experiences after Laryngeal Cancer) were completed. Perceptual analysis using the Grade-Roughness-Breathiness-Asthenia-Strain was performed using the voice recordings. RESULTS: Voice quality remains inferior to the voices of healthy controls both before and up to 24 months post-radiotherapy, demonstrating no statistically significant changes during the study period. Self-perceived communicative function revealed a trend toward improvement. Health-related quality of life remains mostly at stable levels, however, with statistically significant deterioration regarding dry mouth and sticky saliva. Generally, patients reported inferior scores compared to a normal population. CONCLUSION: This study demonstrated no statistically significant changes over time in HRQL and perceptual voice quality at pre-radiotherapy compared to 24 months post-radiotherapy. However, the values remain inferior to the voices of healthy controls or a normal population.

Adaptation and validation of the Persian version of pediatric Voice Handicap Index (pVHI).

BACKGROUND AND OBJECTIVES: This study aimed to assess the reliability and validity of the Persian version of the Pediatric Voice Handicap Index (pVHI). MATERIALS AND METHODS: The questionnaire was translated into Persian and then administrated to the parents of 45 dysphonic children and parents of 135 normal children. The content validity of the questionnaire was confirmed by eight speech-language pathologists. Internal consistency and test-retest reliability were measured via Cronbach's alpha and intra-class correlation coefficient, respectively. Independent-samples t-test was used to evaluate the discriminative and clinical validity of Persian pVHI. RESULTS: Cronbach's coefficient values were excellent for the total score (α = 0.94) and physical subcomponent (α = 0.91). Moreover, these corresponding values were satisfactory for functional (α = 0.82) and emotional (α = 0.79) subcomponents. Test-retest reliability for the total score was high in both dysphonic and control groups (intra-class correlation coefficient> 0.92). There were significant differences between the control and dysphonic groups in terms of the total score and all subcomponents scores of Persian pVHI. However, no significant difference was observed in the mean total score of the Persian pVHI between the control and dysphonic group regarding gender (P < 0.001). DISCUSSION: Persian version of pVHI is a valid and reliable tool to evaluate the severity of voice disorder and its negative effects on the daily life of Persian children with voice disorder from the Parents' viewpoint.

Voice-Related Quality of Life in Patients with Chronic Rhinosinusitis.

OBJECTIVE: Chronic rhinosinusitis (CRS) has long been associated with vocal dysfunction. However, studies quantifying the presence of voice dysfunction in CRS patients or the effects of functional endoscopic sinus surgery (FESS) are sparse. The goal of this study was to determine the voice-related quality of life in patients undergoing FESS for CRS using the validated Voice Related Quality of Life Survey (VRQL). We correlated the preoperative VRQL scores to the Sino-Nasal Outcome Test (SNOT-22) scores, and we determined the effect of FESS on postoperative VRQL scores. METHODS: Consecutive patients undergoing FESS were preoperatively administered both the VRQL and the SNOT-22 surveys. Spearman (ρ) and Pearson (r) correlation coefficients were calculated. The VRQL was mailed to patients postoperatively between 3 and 6 months. The paired t-test was used to compare pre- and post-FESS scores. RESULTS: A total of 102 patients were enrolled, and 81 patients completed the two surveys. A total of 51 (62.9%) patients had raw VRQL score ≥ 10, signifying presence of significant vocal symptoms. The mean ± standard deviation (SD) raw VRQL score of the entire study population was 12.4 ± 4.6, and the mean SNOT-22 score was 37.8 ± 19.2. The Spearman correlation coefficient between VRQL and the total SNOT-22 score was 0.34 (P =.002), and the Pearson correlation coefficient was 0.36 (P = .001). Both correlations were similar, demonstrating that increasing severity of CRS symptoms correlates with decreasing voice-related quality of life (QOL). Seventy patients completed the postoperative survey for an 86% retention rate. Thirty-six of these patients had abnormal preoperative VRQL scores, and these patients improved significantly after FESS. The mean preoperative versus postoperative raw scores were 15.2 ± 5.6 versus 12.5 ± 4.1, respectively (P = .003). CONCLUSION: This study demonstrates the increasing presence of vocal complaints with increasing severity of CRS. It also demonstrates that VRQL scores improve after FESS in those patients with preoperative vocal complaints. LEVEL OF EVIDENCE: IV.

Self-referred personal behavior profile of university professors: association with communicative and vocal self-evaluation. / Perfil de comportamento pessoal autorreferido por professores universitários: associação com a autoavaliação comunicativa e vocal.

PURPOSE: Describe the self-referred personal behavior profiles of university professors and verify the association of these profiles with the self-assessment of communicative aspects and vocal symptoms. METHODS: Study conducted with 334 professors at a public university who responded to an online questionnaire regarding voice use in teaching practice. Personal behavior profile classification was the response variable, which was divided into four types: pragmatic, analytical, expressive and affable. Explanatory variables were vocal self-perception, vocal resources, and communicative aspects. Descriptive data analysis was performed with application of the Pearson's Chi-squared and Fisher's Exact tests. RESULTS: University professors identified themselves more with the affable and expressive personal behavior profiles. Overall, professors presented good self-perception about vocal and communicative aspects, in addition to having reported few vocal symptoms. Profiles differed for some of the assessed variables, namely, pragmatic professors reported high speech velocity and sporadic eye contact; expressive professors demonstrated self-perception about their voice and strong voice intensity; those in the analytical profile self-reported negative perception about vocal quality, weak voice intensity, poor articulation and rapid speaking rate; the other professors mostly reported voice tiredness symptoms and difficulty projecting the voice. CONCLUSION: University professors identify themselves mostly with the affable and expressive profiles. Self-perception analysis of the personal behavior profile in university professors showed the influence of self-reported personality characteristics on communicative skills in the classroom.

OBJETIVO: Descrever o perfil de comportamento pessoal autorreferido por professores universitários, e verificar a associação destes perfis com a autoavaliação dos aspectos comunicativos e sintomas vocais. MÉTODO: Estudo realizado com 334 professores de uma universidade pública que responderam um questionário online referente ao uso da voz na docência. A variável resposta foi a classificação do perfil de comportamento pessoal, identificado em quatro tipos: pragmático, analítico, expressivo e afável, e as variáveis explicativas foram: autopercepção vocal, recursos vocais e aspectos comunicativos. Foi realizada a análise descritiva dos dados, além dos testes Quiquadrado de Pearson e Exato de Fisher. RESULTADOS: Os professores universitários se identificaram mais com os perfis de comportamento pessoal afável e expressivo. De forma geral, os docentes demonstraram boa autopercepção dos aspectos vocais e comunicativos, além de terem relatado poucos sintomas vocais. Os perfis se diferenciaram em algumas variáveis estudadas: o pragmático relatou velocidade de fala rápida e, às vezes, realizar contato de olhos; o expressivo demonstrou autopercepção positiva de sua voz e intensidade forte. Professores com perfil analítico autorreferiram percepção negativa da qualidade vocal, intensidade fraca, articulação ruim e velocidade de fala rápida e, entre os demais perfis, foi o que mais relatou sintomas de cansaço na voz e dificuldade para projetar a voz. CONCLUSÃO: Professores universitários se identificam predominantemente com os perfis afável e expressivo. A análise da autopercepção do perfil de comportamento pessoal em professores universitários mostra a influência das características da personalidade autorreferidas sobre as habilidades comunicativas em sala de aula.

Comparison of the immediate effect of voiced oral high-frequency oscillation and flow phonation with resonance tube in vocally-healthy elderly women. / Comparação do impacto imediato das técnicas de oscilação oral de alta frequência sonorizada e sopro sonorizado com tubo de ressonância em idosas vocalmente saudáveis.

PURPOSE: To verify and compare the immediate effects of the voiced oral high-frequency oscillation (VOHFO) technique and the phonation into a silicone resonance tube in the elderly self-perception of vocal and laryngeal symptoms and in their voice quality. METHODS: 14 elderly women, over 60 years old, performed the VOHFO and phonation into a resonance tube technique (35cm in length and 9mm in diameter) with one-week interval between both to avoid carry-over effect. Initially, all participants answered questions regarding the frequency and intensity of their vocal/laryngeal symptoms. Recordings of the sustained vowel /a/ and counting numbers were performed for posterior perceptual and acoustic analyses of the voice quality. The maximum phonation time (MPT) for /a/, /s/, /z/ and counting numbers were also obtained. After that, a draw lot established which technique (VOHFO or resonance tube) would be initially applied for three minutes. After the exercise performance the same procedures were carried out and the elderly women answered a self-assessment questionnaire about the effect of the techniques in her voice, larynx, breathing and articulation. Comparison pre and post each technique were analyzed using ANOVA, Wilcoxon and Mann-Whitney tests. The sensations after the techniques were assessed using the Chi-square test (p<0.05). RESULTS: The comparison of both techniques showed decrease in roughness and improvement in resonance for counting numbers after the resonance tube and same outcomes post VOHFO. There were no significant differences for the other analyzed variables between groups. CONCLUSION: The phonation into a resonance tube exercise improves the vocal quality of elderly women. In addition, both exercises are similar regarding self-perception of vocal / laryngeal symptoms and sensations post three minutes of the technique, suggesting that VOHFO can be safely applied in voice therapy for this population.

OBJETIVO: Verificar e comparar os efeitos imediatos da técnica de oscilação oral de alta frequência sonorizada (OOAFS) e sopro sonorizado com tubo de ressonância na autopercepção de sintomas vocais/laríngeos e na qualidade vocal de idosas. MÉTODO: Participaram 14 mulheres idosas que realizaram as técnicas OOAFS e sopro sonorizado com tubo de ressonância de silicone, com wash-out de uma semana. Todas responderam questões sobre frequência e intensidade dos sintomas vocais/laríngeos; foram submetidas à gravação da vogal sustentada /a/ e contagem de números, para análise perceptivo-auditiva e acústica vocal. Foram extraídos os tempos máximos de fonação (TMF). Em seguida, sorteou-se a técnica a ser realizada: OOAFS ou tubo de ressonância, por três minutos em tom habitual. Após exercício, os mesmos procedimentos da avaliação inicial foram repetidos e as idosas responderam a um questionário de autoavaliação sobre os efeitos das técnicas. Os dados foram comparados antes e após aplicação das técnicas por meio dos testes ANOVA, Wilcoxon e Mann-Whitney; para as sensações vocais após técnicas, aplicou-se teste Quiquadrado(p<0,05). RESULTADOS: Ao comparar as técnicas, verificou-se diminuição da rugosidade e melhora da ressonância na contagem dos números após tubo de ressonância e manutenção dos resultados após OOAFS. Não houve mais diferenças significantes para as demais variáveis estudadas entre os grupos. CONCLUSÃO: O sopro sonorizado com tubo de ressonância melhora a qualidade vocal de mulheres idosas. Além disso, ambos os exercícios apresentaram semelhanças na autopercepção dos sintomas vocais/laríngeos e sensações, sugerindo que a OOAFS é segura e pode ser empregada na terapia de voz nesta população.

Translation and Validation of Tamil Version of Singing Voice Handicap Index-10 (TSVHI-10).

AIM: To translate and validate the singing voice handicap index (SVHI-10) for the Tamil speaking Indian population and to evaluate the psychometric properties of the Tamil version SVHI-10 (TSVHI-10) in classically trained Carnatic singers. METHOD: Following standard translation, a total of 120 classically trained Carnatic singers: 83 singers without voice complaint and 37 singers with voice complaints answered the Tamil translation of the SVHI-10. RESULTS: The TSVHI -10 scores obatined from classically trained Carnatic singers with and singers without voice complaints were analyzed. SVHI-10 has excellent internal consistency and test retest reliability. Singers without/with voice complaint scored 7.08/22.86 total scores and for each domain Emotional (E): 1.73/5.32, Functional (F): 2.11/7.08, and Physical (P): 3.3/10.35 respectively. CONCLUSION: The TSVHI-10 questionnaire seems to be psychometrically sound and is a valuable instrument for the self-evaluation of handicaps related to voice problems in the context of singing and for making subsequent clinical decisions. The Tamil version of the SVHI-10 was successfully validated as an instrument with proper internal consistency and reliability.

Relationship Between Laryngeal Signs and Symptoms, Acoustic Measures, and Quality of Life in Finnish Primary and Kindergarten School Teachers.

OBJECTIVE: This study investigated the relationship between the acoustic measure smoothed cepstral peak prominence (CPPS), teacher's quality of life as measured by the voice activity and participation profile (VAPP), laryngeal signs and symptoms, voice related health problems and laryngoscopic findings in Finnish teachers. The relationship between CPPS and sound pressure level (SPL) was also assessed. METHODS: Vowel and text samples from 183 healthy Finnish teachers (99 kindergarten teachers [KT] and 84 primary school teachers [PST]) were analyzed for CPPS. Text reading was recorded in conversational loudness by PST, and KT were recorded wearing headphones, while listening to a masking noise of children talking to simulate their classroom voice and environment. CPPS values were correlated with the VAPP, self-reported laryngeal signs and symptoms, voice related health variables, and laryngoscopic findings. RESULTS: There was a significant difference between the two groups for CPPS text, PST showed significantly lower CPPS values (10.44) than KT (11.52). There was no difference between the two groups for CPPS vowel phonation. There was a significant correlation between SPL text and CPPS text for KT (P < 0.001, r = 0.43) but not for PST (P < 0.10, r = 0.16). There was a significant correlation between SPL vowel and CPPS vowel for both PST (P < 0.001, r = 0.47) and KT (P < 0.001, r = 0.45). CPPS did not correlate with the VAPP, laryngeal signs and symptoms, health variables or laryngeal findings. Factorial analysis of variance resulted in a significant relationship between the VAPP, laryngeal signs and symptoms, and teacher type. Teacher type and symptoms had a significant effect on VAPP scores. CONCLUSIONS: In the present work CPPS does not correlate with vocal health indicators of functionally healthy teachers. CPPS was significantly influenced by differences in speaking voice SPL, emphasizing the impact of recording conditions and technique. There was a significant relationship between laryngeal signs and symptoms, teacher type and the VAPP. Laryngeal signs and symptoms and teacher type are important variables and should be included in the clinical evaluation of occupational voice users, and voice problems.

Voice Therapy Outcome-A Randomized Clinical Trial Comparing Individual Voice Therapy, Therapy in Group, and Controls Without Therapy.

OBJECTIVE: A stumbling-block in voice therapy is how the patient will be able to apply the new voice technique in everyday life. Possibly this generalization process could be facilitated by giving voice therapy in group because of the natural forum for training voice-to-speech early in communication between the patients in a group setting. The aim of the study was to compare treatment results from individual voice therapy and voice therapy in group, at several time points and in comparison to patients with no voice therapy. METHODS: A randomized treatment study was performed with 77 consecutive patients diagnosed with a functional voice disorder. Thirty-one patients were randomized to individual and group therapy, respectively, and 15 patients to no therapy. The assessments included standardized voice recording and registration of voice range profile (VRP), answering Voice handicap index (VHI) and visual analogue scales for self-hoarseness and self-vocal fatigue, and perceptual voice evaluation by speech-language pathologist. The assessments were performed before, direct after therapy, and three months later in all groups. The 2 therapy groups were also assessed 12 months after therapy. RESULTS: All VHI scores as well as the self-ratings of hoarseness and vocal fatigue, and the perceptual evaluation of voice quality and maximum VRP improved significantly in both therapy groups 3 months after treatment and at 12 months follow-up. There were no significant changes in the control group, with the exception of decreased self-rated hoarseness and increased maximum VRP. Comparisons between treatment groups showed significant larger improvement after group therapy for VHI physical subscale at 12 months, as well as significant lower VHI total score at all measurement sessions and lower subscale scores at 12 months. There were no differences between treatment groups in self-hoarseness or self-vocal fatigue and no difference in perceptual voice quality or VRP. Comparison between controls and treatment groups showed significant larger change in treatment groups from baseline to three months in VHI total and to end of therapy in functional subscale. Treatment groups also showed significant lower scores than controls at each measurement session, for VHI total and physical subscale as well as lower degree of perceptual aberration of voice quality and vocal fatigue, at three months follow-up. CONCLUSIONS: This study shows long-term improvement from behavioral voice therapy, particularly in a group setting. The results indicate the importance of early transfer-to-speech and late posttherapy test to capture whether the goal of voice therapy was fulfilled or not for the patients.

A Pilot Survey of Warm-Up Practices and Perceptions Among Indian Classical Singers.

OBJECTIVE: Studies have highlighted the importance of having an adequate vocal warm-up exercise regime for prevention of vocal fold injury among singers. Indian classical singing has several singing exercises aimed at improving vocal range and voice. Thus, a need was felt to survey these singers for the warm-up practices they follow and their perception about them. STUDY DESIGN: Cross-sectional study design. METHODS: A 20-item questionnaire was used comprising of questions on demographic details, vocal warm-up singing, and nonsinging-based practices, perceptions about importance of vocal warm-up, and perceptions about effects of vocal warm-up on voice. RESULTS AND CONCLUSION: Fifty Indian classical singers were surveyed. Sixty-four percent of them used vocal warm-up on a daily basis, whereas the remaining did it weekly. Among the singing-based vocal warm-ups, a combination of different singing notes and scales were most commonly used. The popular nonsinging-based warm-up exercises were breathing practice, humming, and meditation. Overall, the singers had a positive perception of the importance of vocal warm-up. Notably, 94% agreed to the importance of having a vocal warm-up regularly before singing. The findings of the present study will help in understanding the existing vocal warm-up regime and perception of the singers. It will benefit counseling singers regarding vocal hygiene, voice care, and management.

A Preliminary Study of Vocal Health Among Collegiate A Cappella Singers.

OBJECTIVE: Collegiate a cappella groups have grown significantly in popularity and prominence; however, there have been few studies that evaluate the vocal health of this subgroup of young singers. The objective of this preliminary study was to conduct a multiparametric evaluation of the vocal health characteristics of a sample of collegiate a cappella singers. We further tested whether differences in vocal health assessments exist between a cappella singers with and without vocal training and trained collegiate singers who do not participate in a cappella groups. STUDY DESIGN: Point prevalence study. METHODS: Forty-one collegiate singers participated in this study. Participants were divided into the following three groups: trained singers (TS), trained a cappella singers (ATS), and untrained a cappella singers (AUS). Participants were administered a set of surveys to assess self-perception of singing voice health and perceived access and attitudes toward voice-related health care. Acoustic and laryngoscopic assessments of participant's speaking and singing voice was performed and validated vocal health questionnaires administered as a means to objectively evaluate for the presence of voice problems. RESULTS: Overall, 87.5% of the ATS and 60% of the AUS groups reported experiencing problems with their singing voice. However, no vocal abnormalities were detected during laryngoscopic and acoustic assessments. Furthermore, minimal differences between any of the measured vocal health parameters were observed between the TS, ATS, and AUS groups. CONCLUSION: Collectively, a high percentage of collegiate a cappella singers with and without vocal training report singing voice problems. However, our sample of a cappella singers did not have increased singing voice problems as compared to vocally trained collegiate singers not in a cappella groups. We did find that a cappella singers may be more inclined to seek information about maintaining a healthy singing voice from their fellow musicians as opposed to singing teachers or other voice health professionals. Singing teachers, otolaryngologists, and speech-language pathologists may need to play a more active role in educating a cappella singers regarding maintaining good vocal health.

Self-assessment of voice outcomes after total thyroidectomy using the Voice Handicap Index questionnaire: Results of a prospective multicenter study.

BACKGROUND: Voice disorders are frequent after thyroidectomy. We report the long-term voice quality outcomes after thyroidectomy using the voice handicap index self-questionnaire. METHODS: Eight hundred patients who underwent total thyroidectomy between 2014 and 2017 in 7 French hospitals were prospectively included. All patients filled in voice handicap index questionnaires, preoperatively and 2 and 6 months after surgery. RESULTS: Median (range) voice handicap index scores were significantly increased at month 2 (4 [0; 108]) compared to preoperative values (2 [0; 76]) and were unchanged at month 6 (2 [2; 92]). Clinically significant voice impairment (voice handicap index score difference ≥18 points) was reported in 19.7% at month 2 and 13% at month 6. Thirty-seven (4.6%) had postoperative vocal cord palsy. In patients with vocal cord palsy compared to those without, median voice handicap index scores were increased at month 2 (14 [0; 107] vs 4 [0; 108]; P = .0039), but not at month 6 (5 [0; 92] vs 2 [0; 87]; P = .0702). Clinically significant impairment was reported in 38% vs 19% at month 2 (P = .010), and in 19% vs 13% at month 6 (P = .310). Thyroid weight, postoperative hypocalcemia, vocal cord palsy, and absence of intraoperative neuromonitoring utilization were associated with an increased risk of clinically significant self-perceived voice impairment at month 2. CONCLUSION: Thyroidectomy impairs patients' voice quality perception in patients with and without vocal cord palsy.

Factors Affecting Initiation of Voice Therapy for Paradoxical Vocal Fold Motion Disorder.

OBJECTIVE: To investigate patient-level predictors of initiation of voice therapy for paradoxical vocal fold motion disorder (PVFM). STUDY DESIGN: Prospective outcomes database study. METHODS: Patients consented to the University of Wisconsin Voice and Swallow Clinics Outcomes Database between March 2010 and November 2016 who were diagnosed with PVFM and recommended for voice therapy were eligible. Patients who attended at least one voice therapy session were considered to have initiated therapy. Analyzed variables included age, gender, distance to the clinic, insurance status, socioeconomic factors, comorbidity score, spirometry results, presence of asthma and/or dysphonia diagnoses, length of evaluation and evaluation model, and patient scores on the Voice Handicap Index and Generalized Anxiety Disorder 7-item scale. RESULTS: One-hundred seventy-eight patients met inclusion criteria. Of these, 118 initiated voice therapy as recommended (66.29%). The majority of patients were female (n = 127; 71.35%). Age was the only factor significantly associated with therapy initiation in both univariate (P = 0.0359) and multivariable (P = 0.0295) analyses, with patients aged 30-39 least likely to attend compared with other age groups. Multivariable analysis also showed that patients evaluated by a speech-language pathologist alone were an estimated three times as likely to initiate therapy compared to patients evaluated by speech-language pathologist and otolaryngologist (ENT) together (P = 0.0407). Other variables were not statistically significant for prediction of therapy initiation. CONCLUSIONS: This study suggests that age group and evaluation model are associated with initiation of voice therapy for PVFM. Further study is needed to investigate social-cognitive and quality-of-life factors in predicting therapy initiation.

Validation of the Arabic version of vocal tract discomfort scale.

Aim: To explore the internal consistency, criterion validity, and discriminative validity of the Arabic version of the vocal tract discomfort scale (VTDS-Arab); and to establish cut-off scores for the VTDS-Arab.Methodology: An overall of 202 participants (31 patients with voice disorders of organic and functional causes, and 171 healthy subjects, mean age 25.3 ± 6.7) were recruited in this study. Participants completed the VTDS-Arab scale and the Arabic version of the voice handicap index (VHI-Arab).Results: The VTDS-Arab had a positive internal consistency confirmed by Cronbach's α = 0.91. The criterion validity of the VTDS-Arab was confirmed by the strong positive correlation between the total scores of the VTDS-Arab and the VHI-Arab (r = 0.64, p < .001). Patients scored higher than the healthy subjects in all the subscales of the VTDS-Arab (p < .001) which confirmed the discriminative validity of the VTDS-Arab. Age and gender were not found to affect the scores of the VTDS as confirmed by Pearson r test (r = 0.02, p = .80) and insignificant p values of Levene's test (F1, 200 = 0.43, p = .51), respectively, which supports the validity of the VTDS-Arab. The study posited interpretations for the ranges of scores of the VTDS-Arab based, where the cut-off score for the VTDS-Arab total was 26.Conclusion: The VTDS-Arab is a reliable and a clinically valid tool that can be used in the evaluation of voice disorders alongside other subjective and objective tools of evaluation.
